Specification of Letters Patent.

Patented Apr. 21, 1914.

Application filed July 22, 1913. Serial No. 780,478.

To all whom it may concern:

Be it known that I, CHARLES J. CRAWFORD, t citizen of the United States, and a resident of the city of Fresno, county of Fresno, and State of California, have invented a new and useful Improvement in Orchard- Plows, of which the following is a. specification.

It is well known among those versed in the art of cultivating orchards that with the means heretofore in use it is diflicult and sometimes impossible to plow the soil near the tree and have a straight draft on the plow. I have overcome this difficulty, and have also incorporated other improvements on a plow of that character which are set forth more in detail below.

In the drawings which accompany this specification Figure 1 is a top view of the plow complete. Fig. 2 is a side view of the plowyFig. 3 is a rear view of the plow, and Fig. 4 is a view of a mold board plow which can be substituted for the disks shown as attached to the plow in Figs. 1, 2, and 3. Fig. 5 shows a bracket attached to the tongue of the cultivator for attaching the draft.

B is the axle of the vehicle which carries a wheel C at one end and wheel C at the other end. I have constructed wheel C very heavy to balance the weight of the plow, and with a flange, the function of which is to keep the plow from slipping.

A is the tongue which is attached to axle B at a point between the lateral center of the axle and wheel C. F is an extension bracket which I prefer to attach to the tongue on the same side and parallel to the shorter end of the axle.

a, b, and c are brace rods which are intended to keep axle B, tongue A and exten sion bracket F in a rigid relationship.

H is a hand lever pivoted to the extension bracket F.

I have attached a plow support K (shown more clearly in Fig. 3) which can carry one or a plurality of disks D, or plows D shown in Fig. 4. Plow support K is attached to extension bracket F and hand lever H by means of a removable swivel pivot or swivel bolt 70. This bolt is adapted to permit the plow support K to have an oscillating motion, and at the same time to secure hand lever H rigidly to such plow support. In my construction I have accomplished this by using a bolt having a square shoulder which fits into the plow support, and a square portion of the length of the bolt immediately under the threads and within the portion passing through hand lever II. By removing the nut on bolt 74, the hand lever H can be lifted therefrom and the plow support K can be turned one-half around, and hand lever I-I then returned to position thus adapting the disks to throw the land to the right or to the left. To further regulate the cut of the. disks I have attached to the outside end of extension bracket F part of toothed wheel (Z having bolt 70 as the center, and have attached to hand lever H a catch which locks at will between such teeth. With this construction it is possible to swing the plow forward or backward when it is desired to turn a wide or narrow furrow, or the plow can be swung out of the way of a tree if desired.

E is a set of eveners which are pivoted to the tongue of the plow.

It will be noted that the theory of having the portion of the axle from the tongue to flange wheel C longer than the portion between the tongue and wheel C is to balance the draft of the plow where extension bracket F is long enough to reach under trees, thus permitting the plowing of ground under trees having low branches under which an ordinary plow could not go. In order to allow a further adjustment, however, I have attached a bracket G to the side of the tongue on which extension bracket F is attached and which is adapted for pivoting the evener thereto in one of a plurality of holes.

f is the seat on which the operator can ride.

What I claim as my invention and upon what I desire Letters Patent is:

1. In an earth working element, the combination of an axle to which a tongue is attached at approximately right angles thereto and at a point nearer one end of said axle than the other; a flange wheel rota-tably carried on the longer end of said aXle and a wheel rotatably carried on the shorter end of such axle, an extension bracket attached to such tongue, and extending beyond the end of the shorter end of such axle, means for adjustably attaching earth working elements to such extension bracket, and means for attaching a draft to such tongue, all substantially as described.

2. In an earth working element of the character described, the combination of an axle With a tongue attached thereto at a point other than the lateral center, a Wheel rotatably attached to each end of such axle, an extension bracket parallel With and on the same side of the tongue as the short end of such axle, means for attaching a draft to said tongue; means for adjustably attaching earth Working elements to the outside end of such extension bracket consisting of a support With a swivel bolt connection passlng through such extension bracket, a hand le ver attach'ed'to such swivel bolt and adapted to lock 'ineither one of a plurality of positions, all substantially as described.

3. In an earth Working element of the character described, the combination of an axle with a tongue attached at approximately right angles thereto at a point other than the lateral center of such axle, a Wheel rotatably attached to each end of such axle,

anextension bracket attached to such tongue on the same side, parallel With and extending beyond the short end of such axle, means for 'adjustably attaching such disks to the outside end of such extension bracket. consisting of a swivel, means for locking such swivel in either one of a plurality of positions, and means for adjustably attaching the draft to the tongue consisting of a bracket having a plurality of holes in a line at right angles to the tongue, and attached to the side of the tongue on which the earth Working elements are attached, all substantially as described.

4. In an earth Working element, the combination of an axle to which a tongue is attached at approximately right angles thereto and at a point nearer one end of said axle than the other, a heavy flanged Wheel rotatably mounted on the longer end of such axle, a light Wheel rotatably mounted on the shorter end of such axle, a bracket extension attached to such tongue on the side opposite such flange wheel, and extending beyond the short end of such axle, means for adjustably attaching earth Working ele ments to such extension bracket, and means for attaching a draft to said tongue, all substantially as described.
